Subject: [PATCH RFC v9 05/51] x86/coco: move CONFIG_HAS_CC_PLATFORM check down into coco/Makefile
Date: Sun, 11 Jun 2023 23:25:13 -0500 [thread overview]
Message-ID: <20230612042559.375660-6-michael.roth@amd.com> (raw)
In-Reply-To: <20230612042559.375660-1-michael.roth@amd.com>
Currently CONFIG_HAS_CC_PLATFORM is a prereq for building anything in
arch/x86/coco, but that is generally only applicable for guest support.
For SEV-SNP, helpers related purely to host support will also live in
arch/x86/coco. To allow for CoCo-related host support code in
arch/x86/coco, move that check down into the Makefile and check for it
specifically when needed.
